You can go on forums such as v3rm and discords that have marketplaces, find some decent accounts and domains that you know will be big and that you can flip and resell them for a higher price. Such as buying a steam account for $10 and reselling that account for $20. That's an easy $10 profit. Doesn't seem like a lot but if you invest the profit you make into more accounts such as 4 letter
Instagram accounts, older Roblox accounts or accounts with cool names, even selling some of your accounts that you don't want anymore will work as well. Example: Remember the yodeling kid? He was at Coachella, he's blown up major in the social media light. If you were on your A-Game you could've made accounts on different platforms named "MasonRamsey" and resold them for a lot of money.
